摘要:
RNA裂解型脱氧核酶是一类具有催化RNA切割活性的DNA分子,其能够以高特异性切割任意RNA底物,并具有高特异性、对基因组无永久影响、设计简单和序列可编程等优点,在生物传感以及疾病治疗方面具有巨大潜力。但脱氧核酶在体内或复杂生物环境中的脱靶激活问题限制了其在应用中的灵敏度和选择性。目前研究主要集中于脱氧核酶的化学修饰改造,通过引入特定的化学基团,来实现对其催化活性的精确控制,并通过将脱氧核酶与适配子结合,以实现其对目标分子的精确识别和高效切割。脱氧核酶序列经过设计后,可用于逻辑运算及分子计算机的开发。现概述脱氧核酶的多种改造和设计方法,结合近年经化学修饰、结构改造的RNA裂解脱氧核酶在疾病治疗及传感领域的应用实例,阐述其在生物传感和基因治疗中的独特性及优越性。探讨RNA裂解脱氧核酶在疾病诊断和治疗中的作用,旨在为该类脱氧核酶在相关领域的进一步应用提供参考。
